TRT and acne: what the evidence says about testosterone-driven breakouts

What did @kmartfit actually say?

The creator claims a "dehydrated greens powder with high doses of chlorophyll" is their personal secret to staying "crystal clear" on TRT for five years. Specifically, they say it "prevents your skin from getting greasy" and "clears the pus from your breakouts." The video ends with a direct pitch: a link in their bio, urgency language about selling out.

Let's be direct: this is a product promotion dressed up as skincare advice. The framing as a "secret" and the sell-out urgency are classic affiliate-marketing cues. That doesn't automatically make the claims false, but it's a reason to look harder at what the evidence actually says before you add anything to your cart.

Does the science back this up?

Weakly, and only in very narrow ways. There is some legitimate research on chlorophyll derivatives and acne, but it doesn't support the sweeping claims made here. A 2015 pilot study by Sigler and Burnett in the Journal of Drugs in Dermatology found topical chlorophyllin gel showed modest improvement in mild-to-moderate acne over three weeks. Topical. Not a greens powder you drink.

On the sebum-production side, which is what "prevents your skin from getting greasy" would require, there is essentially no peer-reviewed evidence that oral chlorophyll supplementation reduces androgen-driven sebaceous gland activity. Testosterone and its conversion to DHT are the primary drivers of sebum overproduction on TRT. A greens drink does not intercept that pathway. A 2021 review by Chilicka et al. in Nutrients looked at dietary interventions and acne and found no studies specifically linking oral chlorophyll intake to sebum reduction.

What did they get wrong (or right)?

They got the underlying problem right: TRT does commonly cause acne. Elevated androgens stimulate sebaceous glands, increase keratinocyte proliferation, and can alter the skin microbiome in ways that promote Cutibacterium acnes overgrowth. That part is well-established, documented by Melnik et al. in a 2018 paper in Experimental Dermatology.

What they got wrong is the mechanism and the solution. Saying chlorophyll powder "prevents your skin from getting greasy" implies it has an anti-androgenic or sebum-suppressing effect. There is no human clinical trial evidence for oral chlorophyll doing this at any dose. The "clears the pus from your breakouts" claim is similarly unsupported for an ingested supplement. Pus in a pustule involves bacterial activity and the inflammatory response. Drinking a greens powder does not directly target either of those things in the way a topical retinoid, benzoyl peroxide, or in more resistant cases a prescription like doxycycline would.

• The acne-on-TRT premise: accurate.
• Chlorophyll reducing oiliness when taken orally: no clinical evidence.
• Chlorophyll clearing pustules when ingested: unsupported by any controlled trial.

What should you actually know?

TRT-related acne is a real and common side effect, and it has real, evidence-backed management options that this video never mentions. For mild cases, topical benzoyl peroxide and salicylic acid remain first-line. For moderate-to-severe cases, dermatologists frequently use topical or oral antibiotics, retinoids, or in some patients adjust the TRT protocol itself, since frequency and dose of testosterone administration can affect peak androgen levels and therefore skin reactivity.

Diet may play a supporting role. There is reasonable evidence, including a 2012 meta-analysis by Bowe and Logan in the Journal of the Academy of Nutrition and Dietetics, that high glycemic load diets and dairy intake can worsen acne. A greens powder might help if it displaces high-glycemic foods in someone's diet, but that's a stretch, and it's not what's being claimed here.

If you're on TRT and dealing with persistent acne, talk to the prescribing provider or a dermatologist. Chlorophyll is not going to fix a hormonal skin problem. It is not dangerous, but it is also not the intervention the evidence points to.

Is there anything actually worth taking from this video?

The acknowledgment that TRT can affect skin is useful. Five years on TRT without serious skin issues is genuinely something some patients manage, though we have no way to verify what's actually driving that for this creator, genetics, protocol management, diet, and skincare routine all interact. A single supplement being the decisive factor is almost certainly an oversimplification. If the greens powder is helping because it supports overall diet quality or hydration, that's plausible but vague. The specific mechanistic claims made here, sebum prevention and pustule clearance from oral chlorophyll, are not supported by the evidence we have.
